T0 all whom t may concern.'

Be it known that I, JOHN N. SGHWALEN, a citizen of the United States, residing at New London, in the county of Kandiyohi and State of Minnesota, have invented certain new and useful Improvements in Sack- Holders; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in sack or bag holders.

The object ofthe invention is to provide a device of this character which will automatically adjust itself to the length of the sack, which is simple, inexpensive and etlicient, and adapted to extend a bag. from side to side as far as possible and yet afford ample space from front to rear to permit the bag to be conveniently filled.

Another obj ect is to provide simple means for laterally adjusting said holder to accommodate bags of varying widths and to vary the tension of the distending means.

With these and others objects in view, the invention consists of certainv novel features of construction, and the combination and arrangement of parts as will be more fully described and claimed.

In the accompanyingr drawings: Figure 1 represents a front elevation of a sack holder constructed in accordance with this invention with a sack shown mounted thereon in dotted lines; Fig. 2 is a side elevation thereof; Fig. 3 is a horizontal section taken on the line 3-3 of Fig. 1; Fig. 4 is a transverse vertical section 4 4 of Fig. 1; Fig. 5 'is a detail perspective view of one of the adjusting blocks; Fig. 6 is a similar view of one of the back supporting and distending hooks or arms.

In the embodiment illustrated a main support or frame is shown in the form of a plate or board 1 provided with a longitudinally extending opening '2 here shown arranged midway the width thereof at its upper end and provided with transversely arranged longitudinally spaced cross bars or rods 3 which are designed to engage a nail or other suitable support for suspending the board `in operative position, a hook 4 being here shown for this purpose. It is of course understood that one of these rods '3 may be engaged with said hook to vary the height of the supporting board according to the length of the bag to be mounted on the holder.

Arranged on opposite sides of the slot 2 are two coiled springs 5 and 6 suspended at their upper ends from suitable fasteners here shown in the form of eyes 7 and having ltheir other ends connected with a vertically movable sliding plate 8, saidsprings being shown connected with said plate by means of eyes 9. This plate 8 as shown is of a width corresponding to the width of the base board 1 and is designed to travel between two laterally extending guides 10 projecting from the oppositel side edges of said plate 1 and'here shown in the form of metal strips secured to said side edges and between the outer free ends of which is mounted a roller 11 between which and the outer face of the member 1 the plate 8 is designed to slide, said'roller being adapted to prevent frictional engagement of the plate 8 and to permit it to move freely between the guides 10. This plate 8 has a roller 12 mounted at its lower end and adapted to travel on the base board 1, said roller being here shown mounted between two longitudinally extending laterally spaced arms 13 formed by -bifurcating the end of the plate 8 as is shown clearly in Fig. 1.

A cross bar or plate 14'issecured to the plate 8 below the guides 10, and the ends thereof extend some distance on opposite sides of said plate and which in connection with the plate 8, forms a carrier for the bag to be supported.

Secured to the opposite ends of the carrier plate 14 are two substantially U-shaped ibolts 15, yone arm 16 of each of which extends through the plate 14 near its upper vedge and is secured in position by nuts 17 and 18 arranged onopposite faces of the plate 14, the nut 18 being here shown coun- -tersunk in the outer face of said plate to prevent turning thereof. The cross bars 19y of these bolts extend transversely of the plate 14 and project at their lower ends beyond the lower edge of said plate with their arms 20 extended inwardly under the lower edge of the plate and sharpened to form bag engaging spurs or hooks which are designed 'tofbe passed through the-hem of the rear edge of the bag as shown in Fig. 2 `and by means of which said edge is held stretched taut between said hooks. Apertured ears Patented May 16, 1916. p

21 extend laterally from the lower edge of the plate 14 in position to receive and form guides for these bolts 15 (see Figs. 1 to 4).

Mounted on the cross bars 19 of the bolts 15 are bag distending members 22 each of which isY exactly alike and hence only one will be described in detail. As shown this member comprises a piece of heavy wire bent intermediately of its ends to form a plurality of spring coils 23 through which the cross bar 19 of the. bolt 15 passes, the upper end 24 of said wire being extended laterally inward toward the base board 1 and provided with a depending right ani gularly disposed linger 25 for a purpose to be described. The other end 26 of said wire is extended laterally outward in a plane at an obtuse ang-le to the plane of the arm or end 24 and is provided at its free end with a laterally extending bag engaging spur 27 which is formed by sharpening the terminal of said arm 26 and bending it laterally outward, said arm having an eye 28 formed therein at a point spaced from the spur 27 and with which is engaged one end of an arm 29 which is here shown also provided with an eye 30 interengaged with the eye 28 of the arm 26, whereby these two arms are securely connected. The arm 29 is connected at its inner end with -the cross bar 19 of the bolt 15 above the spring coils 23 as is shown clearly in Figs. 1 to 4. This arm 29 forms a brace for the arm 26 to assist in suspending the weight of the sack S when filled.

From the above description, it will be obvious that the arm 26 and brace 29 are rigidly connected together at one end and pivotally mounted at the other on the bolt 15- and they are adapted to swing in unison on said bolt forl a purpose to be described.

Mounted on the plate 14 between the bag distending members 22 are two blocks 31 and 32 which are provided at their inner ends with open longitudinally extending slots 33 to receive bolts 34 for adj ustably connecting them on said plate 14. The outer ends of these blocks are beveled on their front faces as shown at 35, being inclined to form bearing faces gradually increasing in thickness from the free ends or edges of said blocks toward the inner edges thereof as is show-n clearly in Figs. 1 and 3 and against which the fingers 25 of the distended members 22 are designed to engage for varying the position of these members 22 to adapt them to be placed closely together or farther apart according to the adjustment of the blocks to provide for their distending bags or sacks of varying widths, it being understood that when the spurs 27 of said members 22 are engaged with the front edge of the sack at opposite ends thereof as shown in Figs. 2 and 3, the engagement of the arms 24 with the beveled faces of the blocks 31 and 32 will vary the position of these members and adapt them to distend and yieldably hold a sack stretched in taut position,A as shown in Fig. 3. Stops for preventing pivotal movement of the blocks 31 anc 32 are here shown in the form of nuts 36 mounted on the ends of bolts 37 which serve to secure the plate 14 to the plate 8, the nuts being arranged adjacent to and just above the upper edges of said blocks and thus perform the double function of securing means for the plate 14 and of stops for preventing the turning movement of the blocks.

In the use of this improved holder, the mouth of a bag or vsack S is first engaged at the rear edge thereof with the spurs 20 formed on the lower ends of the bolts 15, and when one of the spurs 27 of one of the distending members 22 is engaged with the front edge of the sack at a point spaced from the rear edge equal to the length of the arm 26 as is shown clearly in Fig. 3. The other arm 26 is then swung laterally inward against the tension of its spring 23 and the outwardly projecting spur 27 at its end engaged with the front edge of the sack when under the action of the coiled springs 23, these arms 26 will tend to move away from each other and thus hold the sack stretched `in taut position ready for filling, as shown in Fig. 3. To vary the tension of the` 27 may be readily disengaged from "the socket to release the front edge thereof and the spurs 20 to release the rear edge. By connecting the carrier with the base board 1 by means of the coiled springs 5 and 6, said carrier is designed to yield vertically to adapt it to any height of sack and to permit the sack to move downwardly during the filling operation to facilitate the insertion of the contents by positioning its mouth in a more convenient location to receive the material to be inserted.

From the above description it will be obvious that by constructing the holder as described with the coiled springs 5 and 6 for supporting the carrier and the springs 23 for the distending arms, the device is rendered capable of fitting any size bag in a considerable range, as will be readily understood.

I claim as my invention:

1. In a sack holder, the combination of a supporting member, a carrier mounted thereon and comprising a plate having longitudinally spaced members extending transversely thereof and spaced from the outer face thereof, coiled springs mounted on said transversely extending members and having arms at their opposite ends extending laterally in opposite directions, one of said arms Y,

having a bag engaging element at its free end, and adjustable means for engaging the other arm of said coiled springs to vary the positions of the bag engaging elements to adapt them to fit bags of varying widths.
